The Honest Version
Blue light suppresses melatonin, the hormone that tells your body it is time to sleep. Every hour on a screen after dark pushes your sleep window later.
You have probably also seen the headlines saying blue light glasses do nothing. Those studies are real, and they tested clear lenses, the kind that block very little. A randomized trial on properly tinted amber lenses found something different: about thirty minutes more sleep, and less insomnia. Those lenses blocked sixty five percent of blue light.
Lucerna is tinted, and it is built for the digital world. That is the difference.
Which Tint Should You Start With
They are the same frame and the same fit. The only thing that changes is how much light the lens takes out, and the hour that suits
The Lightest Tint
Yellow takes the least out, so colours stay close to normal and most people are happy wearing it out of the house. It is the one to reach for during the working day, when the problem is glare and a screen you cannot get away from rather than sleep.
Best for the working day, long screen sessions, and anyone who wants a lens that still reads as ordinary.
The Everyday Evening Pair
Orange is the one most people end up wearing most. From the moment the sun goes down it takes out enough blue to matter without making the room feel strange, which is why it works for a whole evening rather than just the last stretch of it.
Best for everything after sunset, and the tint most people reach for first.
The Deepest Filter
Red removes the most, and you notice it: whites go warm and the room changes character. That is the trade. It is built for the last hour before bed, when you have a screen in front of you and you would rather it did not push your sleep later.
Best for the last hour before bed, at home, when sleep is the thing you are protecting.
Built To Be Looked At Closely
The most common complaint about blue light glasses is that they feel cheap in the hand. Here is what this one is actually made of
The Hinge
A real metal hinge rather than moulded plastic, not a part that gives out first
The Frame
Cellulose propionate, light enough that you stop noticing you have them on
The Finish
Matte black that stays matte, and does not throw a lamp straight back at you
Frequently Asked Questions
Including the ones that make us look bad
Do these actually work?
+
For sleep, the evidence is genuinely encouraging: trials on tinted amber lenses worn in the evening found more total sleep and less insomnia. For eye strain, the honest answer is that the evidence is weak, and we are not going to pretend otherwise. These are built for your evening, not as a cure for a sore afternoon
I read that blue light glasses are a scam
+
You read a real study. A review of seventeen trials found clear blue light filtering lenses did nothing measurable. Those lenses block very little light, which is why they stay clear. Properly tinted lenses are a different product and were tested separately, with better results. If a pair looks like ordinary clear glasses, it is almost certainly the version that failed those trials
Why does the lens have to be coloured?
+
Because blocking blue means removing blue from the light reaching your eye, and removing blue is what makes a lens look warm. The colour is not styling, it is the evidence that something is actually being filtered
Will I look strange wearing them?
+
The yellow pair reads as an ordinary tinted lens and most people wear it out of the house. Red is much stronger and most people keep it for home in the evening. Having three tints is partly about having one you are happy to be seen in
Are they going to feel cheap?
+
That is the most common complaint in this category and it is a fair thing to ask. The frame is full-rim cellulose propionate with a metal hinge rather than a moulded plastic one. If it arrives and feels like a throwaway pair, send it back inside 30 days and we refund you
Are they prescription?
+
No. They are non-prescription and do not correct vision. They are built to sit comfortably over long sessions at a screen
